This document provides detailed information on the Microchip MCP616/7/8/9 family of operational amplifiers, including their low input offset voltage, low noise, single-supply operation, no phase reversal, and suitability for battery-powered applications.
The MCP616/7/8/9 family of operational amplifiers from Microchip Technology Inc. provides precision, low‑power, single‑supply operation. Features include rail‑to‑rail output swing, ±150 pV maximum input offset voltage, 0.3 nA typical input offset current, and a quiescent current of up to 25 µA.
These devices are offered in single (MCP616), dual (MCP617), and quad (MCP619) configurations with PDIP, SOIC, MSOP and TSSOP packages. Typical applications include battery‑powered instruments, weight scales, strain gauges, medical instruments and test equipment.
